How Do KS-FS Foot Sealers Work?
Our KS-FS impulse sealers fire a short burst of electricity through a specially
designed heating wire to seal the inner walls of bags. The length of the seal time
will depend on the sealing characteristics of the bag being sealed. The sealing
process is simple: The operator places the bag between the sealing jaws and
presses the footswitch to activate the unit. The sealer is equipped with a digital display for easy timer
settings. The seal process ends automatically once the preset seal time is reached. The operator retrieves
the sealed bag and repeats the process. Bags are sealed repeatedly and uniformly.

Operating your Sealer
Assembly Instructions
1. Insert standing tube (Figure 8, Item #7) into the pedal base (Figure 8, Item #1) and connect
with a screw. Make sure the side with two screw holes is facing upwards.
2. Place sealing head in the tube and screw in place using the two long screws (Figure 8, Item #8-
10, 13).
3. Optional: Connect working plate to body using two working bolts. Affix the working table
using the two remaining working bolts.
4. Plug foot switch in the foot switch receptacle found at the back of the machine.
Operation
1. Before operating, check the heating element, PTFE cover, PTFE adhesive and the
silicone rubber.
2. Insert the power cord into the correct receptacle (110V).
3. Turn the power switch on found on the side of the sealer head.
Figure 2. KS-FS Timer Control Panel
4. The red light above the HEAT button should be on. Use the default settings (lowest setting) and
increase gradually as needed. Thicker bags will need a higher setting.
5. Press the COOL button and adjust settings as necessary. The COOL button determines the
congealing time for the sealing. For a high quality seal, seals must be able to cool under pressure.
We usually recommend a congeal setting of at least 2x that of the heat setting but every bag will
have variations. Thicker materials will require a longer cool (congealing) time.

6. Press the AUTO button to adjust recycle settings when the sealer is in automatic mode. This will
determine the time between each seal cycle. Please disregard the AUTO button when using the
sealer in manual mode.
7. Choose the appropriate mode: manual or auto. Press the A/M button to rotate between the
two modes.
a. For manual operation, place the material to be sealed under the sealing arm and press the
foot switch to activate the upper sealing jaw.
b. For auto operation, press the A/M button to activate automatic sealing. To turn off the
automatic mode and return to manual mode, press the A/M button. Auto mode is
when the upper sealing jaw will open and close automatically based on the HEAT,
COOL, and AUTO settings.
Tips for Successful Sealing
1. If the seal is broken or damaged, decrease the sealing time.
2. If the seal is not fully welded, increase the sealing time.
3. If the sealing material sticks to the sealing pad, decrease the congealing time.
4. If the width of the seal is not perfect or does not match the size of the element, increase the
congealing time.
5. Always keep the sealer clean. Remove any residue found on the platform and PTFE cover. Silicone
spray may be used for this purpose.
6. When replacing the heating elements, always replace the PTFE adhesive under
the heating element. A worn PTFE adhesive can cause the heating element to break. The
PTFE adhesive works as a barrier between the body of the sealer and the element. Never allow the
element to come in direct contact with the sealer body as that will damage the timer.
7. Occasionally check the condition of the silicone rubber for wear or burns. A damaged silicone
rubber will affect the quality of the seal.
8. Be sure to turn off the power or unplug the unit before replacing any parts.

Maintenance
The following maintenance procedures should be followed to ensure the longevity of your KS-FS foot
sealer.
Inspection and Cleaning
1. Inspect your machine daily.
2. Use a clean cloth to remove any plastic residue remaining on the PTFE cloth.
3. When replacing the elements, always check the condition of the bottom PTFE tape.
4. Check the condition of the silicone rubber for wear and burns. A damaged silicone rubber will
affect the quality of the seal.
Replacement Kit Instructions
Our KS-FS impulse sealers will require new heating elements and PTFE from time to time. Heating
elements will break through wear and tear. A good rule of thumb is to replace the PTFE adhesive every time
you change your heating element. The PTFE cover prevents the plastic or other thermoplastic material you
are sealing from sticking to the heating element.
Replacement kits are available from your distributor. Kits include (2) heating elements, (2) PTFE adhesives,
and 1ft long roll of PTFE cover. For replacement kit part #s, refer to your model #.

Removing Worn Parts.
1. Loosen the screws on the PTFE cover plate (Figure 8, Item #56).Remove the heating element
cover.
2. Lift up the PTFE cover to expose the heating element (Figure 8, Item #53).

Figure 3. Loosen screws on PTFE plate.
Figure 4. Pull PTFE cover to expose heating element.
3. Remove the heating element by unscrewing the element screw (Figure 8, Item #50) (apply
pressure to the heating element with your finger while unscrewing the screw to prevent the
heating element from twisting).
4. Peel off the PTFE adhesive under the heating element.
Installing New Replacement Parts.
1. Remove the backing of the liner found on the PTFE adhesive.
2. Apply it to the sealer’s sealing platform. The PTFE adhesive must always extend past the sealing
platform by approximately ¼” to ½” on both ends. Bend down the excess on both ends. (The
PTFE adhesive acts a barrier between the metal body and the heating element. Never allow the
heating element to come in direct contact with the sealer’s body because it will damage the timer.)
3. Place a new element on top of the PTFE adhesive by screwing the element in the heating terminal
assembly block. To attach the element to the other side, lift the latch found on the heating
terminal block to push the block inward and securely screw the element to the block. Check the
elements to ensure it is tight and intact.

Figure 6. Lift latch on heating block to screw element in place.
4. Cut off any worn out PTFE cover. Ease out enough footage of PTFE cover to cover the heating
element and extend to the front of the PTFE cover plate.

5. Tighten the screws to affix the PTFE cover plate.
6. If a whole roll of PTFE cover needs to be replaced, loosen the wing nut (Figure 8, Item #46)
found on the plate for PTFE (Figure 8, Item #47) and remove the PTFE roller (Figure 8, Item
#48). Tape one end of the PTFE cover to the rod and roll up the entire piece. Position the PTFE
cover and rod using the plate for PTFE. Ease out enough footage of PTFE cover to cover the
heating element and extend to the front of the PTFE cover plate.
